What Is Crepitus?

Crepitus, sometimes called crepitation (krep-i-tay-shen), describes any grinding, creaking, cracking, grating, crunching, or popping that occurs when moving a joint. People can experience crepitus at any age, but it becomes more common as people get older.

Arthritis—typically either osteoarthritis or rheumatoid arthritis—that causes a joint’s articular cartilage to degenerate. While arthritis often leads to pain, not everyone with joint degeneration will experience it.

When a joint's cartilage degenerates, the joint is no longer adequately protected against friction and impacts. In addition, the loss of cartilage can alter the joint's biomechanics and cause bones to grind against one another. These changes can result in crepitus.

Does Crepitus Need to Be Treated?

Crepitus usually is not a cause for concern. In fact, most people’s joints crack or pop occasionally, and that is considered normal. But if crepitus is regular and is accompanied by pain, swelling, or other concerning symptoms, it may be an indication of arthritis or another medical condition.
